BACKGROUND This disclosure relates generally to wireless communication, and more particularly to parser and interleaving parameter design for resource unit (RU) aggregation.

A wireless local area network (WLAN) may be formed by one or more access points (APs) that provide a shared wireless communication medium for use by multiple client devices, also referred to as stations (STAs). . A basic building block of a WLAN conforming to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards is a basic service set (BSS) managed by an AP. Each BSS is identified by a basic service set identifier (BSSID) advertised by the AP. The AP periodically broadcasts beacon frames, allowing any STAs within the AP's radio range to establish or maintain a communication link with the WLAN.

[0004] In some examples, a wireless communication system (eg, WLAN) is capable of high efficiency (HE) WLAN operations (as defined in IEEE 802.11ax) or extremely high throughput (EHT) (as defined in IEEE 802.11be). ) configured for APs and STAs. In some resource deployments, a wireless communication system can support both licensed and unlicensed communication, as well as frequency bands typically used by Wi-Fi technology (such as the 2.4 GHz band or 5 GHz band). Frequency bands (eg, 6 GHz band) may be supported. Each of the frequency bands may include multiple subbands or frequency channels for signaling physical layer convergence procedure (PLCP) protocol data units (PPDUs). PPDUs may be transmitted over a wireless channel by a STA or an AP. In some examples, the PPDUs may be transmitted over a wireless channel with a minimum bandwidth of 20 MHz. In other examples, the extended BSS bandwidth may be formed through channel bonding, and PPDUs may be transmitted over wireless channels with bandwidths of 40 MHz, 80 MHz, 160 MHz or 320 MHz.

In some examples, existing technologies (eg, fifth generation (5G) systems, which may be referred to as fourth generation (4G) systems, such as Long Term Evolution (LTE) systems and New Radio (NR) systems) may occupy the resources of the extended BSS bandwidth. As a result, the AP or STA may have difficulty finding a continuous idle channel (eg, a continuous 80 MHz, 160 MHz, or 320 MHz channel) for EHT operations within the extended BSS bandwidth. STAs or APs may experience reduced signaling throughput due to overlapping data traffic, and available frequency resources may be wasted, especially in the case of single-user transmissions.

[0006] The systems, methods, and devices of the present disclosure each have several innovative aspects, no single one of which is solely responsible for the desirable attributes disclosed herein.

One innovative aspect of the subject matter described in this disclosure may be implemented as a method for wireless communication at a receiving wireless device (eg, an access point (AP) or station (STA)). As described herein, the available frequency spectrum (eg, extended Basic Service Set (BSS) bandwidth) of a wireless channel may be divided into multiple resource units (RUs), each RU having a number of different frequencies. subcarriers ("tones"). The receiving wireless device may determine an allocation of multiple RUs, where the multiple RUs are associated with two or more bandwidth segments of the total bandwidth allocation. Subsequently, the receiving wireless device may determine a first value of the parameter for the tone configuration of the multiple RUs aggregated together, wherein the first value of the parameter is for individual RUs of the aggregated multiple RUs. different from the individual values of the parameter. In some implementations, the parameter can include a tone mapping distance (D _TM ) value, the location of the pilot tones, or both. Additionally, the location of the pilot tones, the number of pilot tones, and the D _TM value may be based on the total number of pilot tones, or may be based on reusing a subset of pilot tones as data tones (eg, one or more data tones are not available in the punctured portion of multiple RUs) or both. The receiving wireless device may then receive the set of coded bits of the data unit via the multiple RUs according to the tone configuration indicated by the first value of the parameter.

Another innovative aspect of the subject matter described in this disclosure may be implemented in a method for wireless communication at a transmitting wireless device (eg, an AP or a station (STA)). In some implementations, the transmitting wireless device can also determine an assignment of the multiple RUs and a first value of the parameter to the tone configurations of the multiple RUs aggregated together. Additionally, the transmitting wireless device may distribute the set of coded bits to the multiple RUs based on the first value of the parameter. Subsequently, the transmitting wireless device may transmit the distributed set of coded bits over the multiple RUs. In some implementations, multiple RUs may be aggregated together for single-user (SU) transmission or for orthogonal frequency-division multiple access (OFDMA) uplink or downlink scenarios.

The wireless communication device may determine a data parsing and encoding scheme for distributing bits of the data payload across the aggregated set of RUs. For example, the wireless communication device may determine a value of a parameter for distributing bits of a data payload across the aggregated set of RUs based on the aggregated set of RUs, where the value of the parameter is different from the values of the same parameter for each of the RUs constituting the grated set of RUs.

For example, the wireless communication device may sum the number of pilot tones in each RU of the aggregated set of RUs, where the value of the parameter is the total number of pilot tones from each of the RUs. Additionally or alternatively, the wireless communication device may select a subset of pilot tones from the aggregated set of RUs and may reuse the subset of pilot tones as data tones for distribution of bits of the data payload. have. In some implementations, the wireless communication device can reuse a subset of the pilot tones as data tones based on one or more of the data tones being punctured and not available for distribution of bits of the data payload.

To perform passive scanning, the STA 104 is transmitted by the individual APs 102 in a periodic time interval referred to as a target beacon transmission time (TBTT) (measured in time units (TUs)). Listen to beacons. In some examples, one TU may be equal to 1024 microseconds (μs). To perform active scanning, the STA 104 generates and sequentially transmits probe requests on each channel to be scanned, and listens for probe responses from the APs 102 . Each STA 104 , identifies or selects an AP 102 to associate based on scanning information obtained through passive or active scans, and authenticates and associates to establish a communication link 108 with the selected AP 102 . may be configured to perform operations. The AP 102 assigns the STA 104 an association identifier (AID) at the apex of the association operations that the AP 102 uses to track the STA 104 .

As a result of the increasing ubiquity of wireless networks, the STA 104 selects one of many BSSs within range of the STA or multiple APs that together form an extended service set (ESS) comprising multiple connected BSSs. You may have the opportunity to choose from among 102 . The extended network station associated with the WLAN 100 may be connected to a wired or wireless distribution system that may allow multiple APs 102 to connect in this ESS. Thus, a STA 104 may be covered by more than one AP 102 and may be associated with different APs 102 at different times for different transmissions. Additionally, after associating with the AP 102 , the STA 104 may also be configured to periodically scan its surroundings to find an AP 102 more suitable to associate with. For example, a STA 104 that is moving relative to its associated AP 102 may be the other AP 102 having more desirable network characteristics, such as a larger received signal strength indicator (RSSI) or reduced traffic load. A “roaming” scan can be performed to discover

In some cases, the STAs 104 may form networks without equipment other than the APs 102 or the STAs 104 itself. An example of such a network is an ad hoc network (or wireless ad hoc network). ad hoc networks may alternatively be referred to as mesh networks or peer-to-peer (P2P) networks. In some cases, ad hoc networks may be implemented within a larger wireless network, such as WLAN 100 . In such implementations, the STAs 104 may communicate with each other via the AP 102 using communication links 108 , but the STAs 104 may also communicate directly with each other via direct wireless links 110 . can communicate. Additionally, two STAs 104 may communicate over the direct wireless link 110 regardless of whether both STAs 104 are associated with and served by the same AP 102 . In such an ad hoc system, one or more of the STAs 104 may infer the role played by the AP 102 of the BSS. Such a STA 104 may be referred to as a group owner (GO) and may coordinate transmissions within an ad hoc network. Examples of direct wireless links 110 include Wi-Fi direct connections, connections established by using a WiFi Tunneled Direct Link Setup (TDLS) link, and other P2P group connections.

[0077] APs 102 and STAs 104 are the IEEE 802.11-2016 specification or revisions thereof (including but not limited to, 802.11ay, 802.11ax, 802.11az, 802.11ba, and 802.11be). function and communicate (via individual communication links 108) according to a family of IEEE 802.11 wireless communication protocol standards (as defined by These standards define WLAN radio and baseband protocols for the PHY and medium access control (MAC) layers. APs 102 and STAs 104 communicate wirelessly (hereinafter also referred to as “Wi-Fi communications”) in the form of PHY protocol data units (PPDUs) (or physical layer convergence protocol (PLCP) PDUs). referred to) transmit and receive from each other. APs 102 and STAs 104 in WLAN 100 may transmit PPDUs over the unlicensed spectrum, which includes the 2.4 GHz band, the 5 GHz band, the 60 GHz band, the 3.6 GHz band, and the 900 MHz band. It may be part of the spectrum that includes frequency bands commonly used by the same Wi-Fi technology. Some implementations of APs 102 and STAs 104 described herein may also communicate in other frequency bands, such as the 6 GHz band, which may support both licensed and unlicensed communications. APs 102 and STAs 104 may also be configured to communicate over other frequency bands, such as shared licensed frequency bands. In some examples, multiple operators may have a license to operate in the same or overlapping frequency band or bands.

Each of the frequency bands may include multiple subbands or frequency channels. For example, PPDUs conforming to IEEE 802.11n, 802.11ac, 802.11ax, and 802.11be standard revisions may be transmitted over the 2.4, 5 GHz, or 6 GHz bands, each of which may be split into multiple 20 MHz channels. Accordingly, these PPDUs are transmitted through a physical channel having a minimum bandwidth of 20 MHz, but larger channels can be formed through channel bonding. For example, PPDUs may be transmitted over physical channels with bandwidths of 40 MHz, 80 MHz, 160 MHz or 320 MHz by bonding multiple 20 MHz channels together.

[0079] Each PPDU is a complex structure including a payload and a PHY preamble in the form of a PSDU (PHY service data unit). The information provided in the preamble can be used by the receiving vice to decode subsequent data of the PSDU. In cases where PPDUs are transmitted over a bonded channel, the preamble fields may be duplicated and transmitted in each of multiple component channels. The PHY preamble may include both a legacy portion (or “legacy preamble”) and a non-legacy portion (or “non-legacy preamble”). The legacy preamble can be used for packet detection, automatic gain control and channel estimation, among other uses. The legacy preamble may also be used to maintain compatibility with legacy devices in general. The format and coding of the information provided in the non-legacy portion of the preamble is based on the specific IEEE 802.11 protocol that will be used to transmit the payload.

2A shows an example protocol data unit (PDU) 200 usable for wireless communication between an AP and one or more STAs. For example, the PDU 200 may be configured as a PPDU. As shown, the PDU 200 includes a PHY preamble 202 and a PHY payload 204 . For example, the preamble 202 may include a legacy portion, which itself consists of a legacy short training field (L-STF) 206, which may consist of two BPSK symbols, and two BPSK symbols. It includes a legacy long training field (L-LTF) 208, and a legacy signal field (L-SIG) 210 that may consist of two BPSK symbols. The legacy portion of the preamble 202 may be constructed according to the IEEE 802.11a wireless communication protocol standard. The preamble 202 also includes a non-legacy portion comprising one or more non-legacy fields 212 conforming to an IEEE wireless communication protocol, such as, for example, IEEE 802.11ac, 802.11ax, 802.11be or later wireless communication protocol standards. can do.

The L-STF 206 generally enables a receiving device to perform automatic gain control (AGC) and coarse timing and frequency estimation. L-LTF 208 generally enables a receiving device to perform precise timing and frequency estimation and also to perform initial estimation of a wireless channel. L-SIG 210 generally enables a receiving device to determine the duration of a PDU and use the determined duration to prevent transmissions other than PDUs. For example, the L-STF 206 , the L-LTF 208 , and the L-SIG 210 may be modulated according to a binary phase shift keying (BPSK) modulation scheme. The payload 204 may be modulated according to a BPSK modulation scheme, a quadrature BPSK (Q-BPSK) modulation scheme, an auadrature amplitude modulation (QAM) modulation scheme, or other suitable modulation scheme. The payload 204 may include a PSDU comprising a data field (DATA) 214 , which in turn is in the form of, for example, medium access control (MAC) protocol data units (MPDUs) or aggregated MPDUs (A-MPDUs). to carry higher layer data.

FIG. 2B shows an exemplary L-SIG 210 of the PDU 200 of FIG. 2A . The L-SIG 210 includes a data rate field 222 , a reserved bit 224 , a length field 226 , a parity bit 228 and a tail field 230 . Data rate field 222 indicates a data rate (it should be noted that the data rate indicated in data rate field 222 may not be the actual data rate of the data carried in payload 204). The length field 226 indicates the length of the packet in, for example, symbols or bytes. The parity bit 228 may be used to detect bit errors. The tail field 230 includes tail bits that may be used by the receiving device to terminate operation of a decoder (eg, a Viterbi decoder). The receiving device may utilize the data rate and the length indicated in the data rate field 222 and the length field 226 to determine the duration of the packet, such as in units of microseconds (μs) or other units of time.

The PDU 300 may further include a PHY payload 306 after the preamble, for example in the form of a PSDU including a DATA field 324 . The legacy portion 302 of the preamble includes an L-STF 308 , an L-LTF 310 , and an L-SIG 312 . The non-legacy portion 304 and DATA field 374 of the preamble may be formatted as a HE WLAN preamble and frame, respectively, according to the IEEE 802.11ax revision to the IEEE 802.11 wireless communication protocol standard.

In contrast, HE-SIG-B 318 may be unique to each 20 MHz channel and may target specific STAs 104 .

The RL-SIG 314 may indicate to the HE-compatible STAs 104 that the PPDU is a HE PPDU. The AP 102 uses the HE-SIG-A 316 to identify the multiple STAs 104 and notify the multiple STAs that the AP has scheduled UL or DL resources for the multiple STAs 104 . 104) may be notified. HE-SIG-A 316 may be decoded by each HE-compatible STA 104 served by AP 102 . HE-SIG-A 316 includes information usable by each identified STA 104 to decode the associated HE-SIG-B 318 . For example, HE-SIG-A 316 is a frame including locations and lengths of HE-SIG-Bs 318 , available channel bandwidths and modulation and coding schemes (MCS), among other possibilities. Format can be displayed. HE-SIG-A 316 may also include HE WLAN signaling information usable by STAs 104 other than multiple identified STAs 104 .

The HE-SIG-B 318 may carry STA-specific scheduling information, such as, for example, per-user MCS values and per-user RU allocation information. In the context of DL MU-OFDMA, this information enables individual STAs 104 to identify and decode corresponding RUs in the associated DATA field. Each HE-SIG-B 318 includes a common field and at least one STA-specific (“user-specific”) field. Among other possibilities, the common field may indicate RU allocations to multiple STAs 104 , may indicate RU allocations in the frequency domain, and may indicate which RUs are allocated for MU-MIMO transmissions. and may indicate which RUs correspond to MU-OFDMA transmissions, and may indicate the number of users in assignments. The common field may be encoded with common bits, CRC bits and tail bits. User-specific fields are assigned to specific STAs 104 and may be used to schedule specific RUs and indicate scheduling to other WLAN devices. Each user-specific field may include multiple user block fields, which may be followed by padding. Each user block field may include two user fields containing information about two individual STAs to decode their respective RU payloads in a DATA field 324 .

The PPDU 350 may be used for SU, MU-OFDMA or MU-MIMO transmissions. The PPDU 350 includes a PHY preamble that includes a legacy portion 352 and a non-legacy portion 354 . The PPDU 350 may further include a PHY payload 356 after a preamble in the form of a PSDU including, for example, a DATA field 376 . Legacy portion 352 includes L-STF 358 , L-LTF 360 , and L-SIG 362 . The non-legacy portion 354 and DATA field 376 of the preamble may be formatted as an EHT WLAN preamble and frame, respectively, according to the IEEE 802.11be revision to the IEEE 802.11 wireless communication protocol standard, or a future IEEE 802.11 wireless communication protocol It may be formatted as a preamble and frame, respectively, compliant with any post-HE version of a new wireless communication protocol that conforms to the standard or other standards.

EHT-SIG-A 368 may further include a tail (eg, 6 bits) and a cyclic redundancy check (CRC) (eg, 4 bits) that may be used for binary convolutional code (BCC).

The EHT-SIG-B 370 may include multiple symbols, which may be encoded in a different block than the block in which the EHT-SIG-A 368 is encoded. In some other implementations, EHT-SIG-A 368 may be co-encoded with some or all of EHT-SIG-B 370 . For example, EHT-SIG-A 368 may be co-encoded with a first portion of EHT-SIG-B 370 containing information common to all users served by PPDU 350 . The EHT-SIG-B 370 may carry STA-specific scheduling information, such as, for example, per-user MCS values and per-user RU allocation information. The EHT-SIG-B 370 may generally be used by the receiving device to interpret the bits of the DATA field 376 . In the context of DL MU-OFDMA, this information enables individual STAs 104 to identify and decode corresponding RUs in the associated DATA field 376 . Each EHT-SIG-B 370 includes a common field and at least one STA-specific (“user-specific”) field. Among other possibilities, the common field may indicate RU allocations to multiple STAs 104 , may indicate RU allocations in the frequency domain, and may indicate which RUs are allocated for MU-MIMO transmissions. and may indicate which RUs correspond to MU-OFDMA transmissions, and may indicate the number of users in assignments. The common field may be encoded with common bits, CRC bits and tail bits. User-specific fields are assigned to specific STAs 104 and may be used to schedule specific RUs and indicate scheduling to other WLAN devices. Each user-specific field may include multiple user block fields, which may be followed by padding. Each user block field may include two user fields containing information for two individual STAs, for example, to decode the respective RU payloads of the two individual STAs.

For example, Pre-SIG 366 may be used by a receiving device to interpret bits of one or more of EHT-SIG-A 368 , EHT-SIG-B 370 , or DATA field 376 . In some implementations, Pre-SIG 366 includes a reserved bit that indicates whether PPDU 350 complies with, for example, the IEEE 802.11 wireless communication protocol standard or EHT or a later version of another family of standards (eg, after IEEE 802.11ax). may include In some implementations, Pre-SIG 366 includes a version field that includes at least one bit indicating a particular wireless communication protocol version to which PPDU 350 conforms.

4 shows an example PPDU 400 usable for communications between an AP 102 and one or more STAs 104 . As described above, each PPDU 400 includes a PHY preamble 402 and a PSDU 404 . Each PSDU 404 may represent (or “carry”) one or more MPDUs 416 . For example, each PSDU 404 may carry an aggregated MPDU (A-MPDU) 406 that includes an aggregation of multiple A-MPDU subframes 408 . Each A-MPDU subframe 406 is a MAC delimiter prior to a subsequent MPDU 416 containing the data portion (“payload” or “frame body”) of the MPDU frame 410 . ) 412 and an MPDU frame 410 including a MAC header 414 . Each MPDU frame 410 also includes a frame check sequence (FCS) field 418 for error detection (eg, the FCS field may include a cyclic redundancy check (CRC)) and padding bits 420 . can do. The MPDU 416 may carry one or more MAC service data units (MSDU) 416 . For example, the MPDU 416 may carry an aggregated MSDU (A-MSDU) 422 that includes a number of A-MSDU subframes 424 . Each A-MSDU subframe 424 includes a corresponding MSDU 430 , which follows the subframe header 428 and precedes padding bits 432 .

Referring back to the MPDU frame 410 , the MAC delimiter 412 may serve as a marker of the beginning of the associated MPDU 416 , and may indicate the length of the associated MPDU 416 . The MAC header 414 may include a number of fields containing information that defines or indicates characteristics or properties of the data encapsulated within the MPDU 416 . The MAC header 414 includes at least a duration field that indicates a duration that extends from the end of the PPDU to the end of an acknowledgment (ACK) or block ACK (BA) of the PPDU that should be transmitted by the receiving wireless communication device. The use of the Duration field serves to reserve the wireless medium for the indicated duration and enables the receiving device to set its own network allocation vector (NAV). MAC header 414 also includes a number of fields indicating addresses for data encapsulated in MPDU 416 . For example, the MAC header 414 may include a combination of a source address, a transmitter address, a receiver address, or a destination address. The MAC header 414 may further include a frame control field including control information. The frame control field may specify a frame type, such as a data frame, a control frame, or a management frame.

APs and STAs that include multiple antennas may support various diversity schemes. For example, spatial diversity may be used by one or both of the transmitting device or the receiving device to increase the robustness of the transmission. For example, to implement a transmit diversity scheme, a transmitting device may transmit the same data redundantly via two or more antennas. APs and STAs that include multiple antennas may also support space-time block coding (STBC). Using STBC, the transmitting device also transmits multiple copies of the data stream via multiple antennas, increasing the likelihood of decoding correct data using the various received versions of the data. More specifically, the data stream to be transmitted is encoded into blocks, which are distributed between spaced apart antennas and over time. In general, STBC may be used when the number of transmit antennas N _Tx exceeds the number of spatial streams N _SS (described below). The N _SS spatial streams may be mapped to N _STS space-time streams, which are then mapped to N _Tx transmit chains.

APs and STAs that include multiple antennas may also support spatial multiplexing, which may be used to increase spectral efficiency and resulting transmission throughput. To implement spatial multiplexing, the transmitting device divides the data stream into N _SS separate independent spatial streams. The spatial streams are then individually encoded and transmitted in parallel via multiple N _Tx transmit antennas. If the transmitting device includes N _Tx transmit antennas and the receiving device includes N _Rx receive antennas, then the maximum number of spatial streams that the transmitting device can transmit to the receiving device simultaneously N _SS is one of N _Tx and N _Rx limited to small values. In some implementations, the AP 102 and STAs 104 may be capable of implementing both spatial multiplexing as well as transmit diversity. For example, in cases where the number of spatial streams N _SS is smaller than the number of transmit antennas N _Tx , to realize transmit diversity, the spatial streams may be multiplied by a spatial extension matrix.

APs and STAs that include multiple antennas may also support beamforming. Beamforming refers to focusing the transmit energy in the direction of a target receiver. Beamforming is not only used in single-user contexts, for example to improve signal-to-noise ratio (SNR), but also MU-MIMO (also referred to as spatial division multiple access (SDMA)) may be used in a multi-user (MU) context to enable multiple-input multiple-output) transmissions. To perform beamforming, a transmitting device, referred to as a beamformer, transmits a signal from each of a plurality of antennas. A beamformer configures the amplitude of these signals and phase shifts between signals transmitted from different antennas so that the signals are additively added along specific directions towards the intended receiver, referred to as a beamformee. The way the beamformer configures the amplitudes and phase shifts depends on the channel state information (CSI) associated with the radio channels the beamformer is going to communicate with the beamformer.

[0096] In order to acquire CSI required for beamforming, the beamformer may perform a beamformer and a channel sounding procedure. For example, the beamformer may transmit one or more sounding signals (eg, in the form of a null data packet (NDP)) to the beamformer. Then, the beamformer may perform measurements on each of the N _Tx x N _Rx sub-channels corresponding to both of the transmit antenna and the receive antenna pairs based on the sounding signal. The beamformer generates a feedback matrix based on channel measurements, and typically compresses the feedback matrix before sending the feedback to the beamformer. The beamformer then generates a precoding (or “steering”) matrix for the beamformer based on the feedback and precodes the data streams to construct amplitudes and phase shifts for subsequent transmissions to the beamformer. A steering matrix can be used.

As described above, the transmitting device may support the use of diversity schemes. When performing beamforming, the transmit beamforming array gain is logarithmically proportional to the ratio of N _Tx to N _SS . Therefore, it is generally desirable to increase the number of transmit antennas N _Tx when performing beamforming to increase gain within other constraints. It is also possible to more accurately direct transmissions by increasing the number of transmit antennas. This is particularly advantageous in MU transmission contexts where reducing interference between users is particularly important.

As described above, APs 102 and STAs 104 are capable of multi-user (MU) communications, ie, simultaneous transmissions from one device to each of multiple devices (eg, AP ( Multiple simultaneous downlink (DL) communications from 102 to corresponding STAs 104 ) or simultaneous transmissions from multiple devices to a single device (eg, from corresponding STAs 104 to AP 102 ). multiple simultaneous uplink (UL) transmissions). To support MU transmissions, APs 102 and STAs 104 may utilize MU-MIMO and MU orthogonal frequency division multiple access (MU-OFDMA) techniques.

[0099] In MU-OFDMA schemes, the available frequency spectrum of a wireless channel may be partitioned into multiple resource units (RUs) each containing a number of different frequency subcarriers (“tones”). Different RUs may be assigned or assigned to different STAs 104 by the AP 102 at certain times. The sizes and distributions of RUs may be referred to as RU allocation. In some implementations, RUs may be allocated in 2 MHz intervals, so the smallest RU may contain 26 tones consisting of 24 data tones and 2 pilot tones. Consequently, in a 20 MHz channel, up to 9 RUs (eg, 2 MHz, 26-tone RUs) may be allocated (because some tones are reserved for other purposes). Similarly, in a 160 MHz channel, a maximum of 74 RUs may be allocated. Larger 52 ton, 106 ton, 242 ton, 484 ton and 996 ton RUs may also be allocated. Adjacent RUs can be separated by null subcarriers (such as DC subcarriers), for example, to reduce interference between adjacent RUs, reduce receiver DC offset, and avoid transmit center frequency leakage. have.

In the case of UL MU transmissions, the AP 102 may transmit a trigger frame to initiate and synchronize a UL MU-OFDMA or UL MU-MIMO transmission from multiple STAs 104 to the AP 102 . have. Accordingly, such trigger frames may enable multiple STAs 104 to transmit UL traffic to the AP 102 simultaneously in time. The trigger frame may address one or more STAs 104 via respective association identifiers (AIDs), and one or more RUs that may be used to transmit UL traffic to the AP 102 each AID (and thus each STA 104 ). The AP may also designate one or more random access (RA) RUs with which unscheduled STAs 104 may contend.

5 illustrates an example of a wireless communication system 500 that supports a parser and interleaving parameter design for RU aggregation, in accordance with aspects of the present disclosure. The wireless communication system 500 may include an AP 102 - a and a STA 10 - a , which may be examples of corresponding devices described with reference to FIG. 1 . For example, the AP 102 - a and the STA 10 - a may correspond to a BSS managed by the AP 102 - a . In some examples, the BSS may include one or more additional sets of STAs 104 within range of the AP 102 - a , with an established association.

The AP 102 - a may support an example coverage area 10 - a , which may represent a BSS for the wireless communication system 500 . The AP 102 - a and the STA 10 - a may communicate via a communication link (or “Wi-Fi link”) 108 - a. In some examples, the communications are multi-user (MU) communications, ie, simultaneous transmissions from one device to each of multiple devices (eg, multiple transmissions from an AP 102 - a to corresponding STAs 104 ). simultaneous downlink communications) or simultaneous transmissions from multiple devices to a single device (eg, multiple simultaneous uplink transmissions from the corresponding STAs 104 to the AP 102 - a ). To support multi-user (MU) transmissions, the AP 102 - a and one or more STAs 104 may utilize MU-MIMO and MU-OFDMA techniques. In other examples, as shown, the communication may correspond to single-user communications and may include sequential communication between the AP 102 - a and the STAs 10 - a . To support single-user transmissions, the AP 102 - a and the STA 10 - a may utilize single-user MIMO (SU-MIMO) and single-user OFDMA (SU-OFDMA) techniques.

In some examples, the wireless communication system 500 is configured with a resource deployment or resources associated with one or more existing technologies (eg, 4G systems such as LTE systems and 5G systems, which may be referred to as NR systems). It may include the deployment of resources used for overlapping Wi-Fi technologies. The AP 102 - a and the STA 10 - a may be HE supported devices and may be configured for 802.11ax, 802.11be, or EHT operation for resource deployment. For example, the AP 102-a and the STA 104-a may transmit single-user PPDUs in the unlicensed spectrum, which includes the 2.4 GHz band, the 5 GHz band, the 60 GHz band, the 3.6 GHz band, and 900 It may be a portion of the spectrum that includes frequency bands commonly used by Wi-Fi technology, such as the MHz band. Additionally or alternatively, the AP 102 - a and the STA 10 - a may communicate in other frequency bands, such as the 6 GHz band, which bands may support both licensed and unlicensed communications. Each of the frequency bands carries single-user PPDUs and may include multiple subbands or frequency channels spanning a minimum bandwidth of 20 MHz.

Based on the supported HE operation, the AP 102 - a and the STA 10 - a may transmit single-user PPDUs over the extended BSS bandwidth 505 , which may be formed through channel bonding. have. Based on channel bonding, the extended BSS bandwidth 505 may span a frequency spectrum of 40 MHz, 80 MHz, 160 MHz, or 320 MHz. In some examples, data traffic associated with existing technologies or proximate AP 102 and STA 104 communications within OBSS may occupy frequency resources of the extended BSS bandwidth 505 . As a result, the AP 102 - a and the STA 10 - a are a continuous idle channel (eg, a continuous 80 MHz, 160 MHz, or 320 MHz channel) for HE or EHT operations over the communication link 108 - a. may be difficult to find.

In some implementations, the AP 102 - a and the STA 10 - a are in the primary or non-primary of the OFDMA mode or extended BSS bandwidth 505 managed by the AP 102 - a . It may support a preamble puncturing mode in which the frequency channel is zero-out as part of the PHY preamble included for PPDUs. Moreover, the AP 102 - a and the STA 10 - a may support flexible channel aggregation for transmitting single-user PPDUs over a non-contiguous frequency channel included within the extended BSS bandwidth 505 . . That is, multiple RUs may be assigned to the same user, where the multiple RUs may include single-user transmission over a punctured bandwidth that includes multiple RUs that are either contiguous or non-contiguous, or both. have. Additionally or alternatively, multiple RUs may be assigned to multiple users for MU-OFDMA transmissions, and each user is assigned to have multiple RUs, either contiguous, noncontiguous, or both. For example, the available frequency spectrum of the extended BSS bandwidth 505 may be partitioned into a number of contiguous or non-contiguous RUs each comprising a number of different frequency subcarriers (“tones”). Different RUs may or may be assigned by the AP 102 - a at specific times. The sizes and distributions of RUs may be referred to as RU allocation. As part of flexible channel aggregation, the AP 102 - a may allocate multiple non-adjacent RUs as part of the RU aggregation. That is, the STA 104-a may be assigned a number of adjacent or non-adjacent RUs for signaling through a frequency channel of RU aggregation.

[0106] To support RU aggregation, the AP 102 - a or the STA 10 - a may determine a data parsing and encoding scheme for distributing and encoding information bits of a PSDU data payload. For example, as part of the downlink single-user PPDU, the AP 102 - a may identify at least a data rate field, a length field, and a tail field for the PPDU. Based on the identification, the AP 102 - a may calculate the number of OFDM symbols included in the DATA field assigned to the STA 10 - a .

Based on the minimum number of OFDM symbols (N _{sym_init} ), the AP 102 - a may determine a number equal to the total number of data payloads (N _pld ). The variable N _pld may be based on RU aggregation and may correspond to the product of N _{sym_init} and the number of data bits per OFDM symbol (N _DBPS ) as indicated in the data rate field of the PPDU. Furthermore, the AP 102 - a may then determine the number of symbols based on low-density parity-check (LDPC) encoding parameters of the one or more RUs. For example, the AP 102 - a may determine a binary bit flag to indicate whether the LDPC codewords overflow with one or more additional OFDM symbols (N _{ldpc_ext} ). If an additional symbol is used for any LDPC encoded RU, all LDPC RUs in the aggregation may add the additional symbol. Moreover, BCC encoding to support timing alignment when both LDPC and binary convolutional code (BCC) encoding are allowed for different RUs of RU aggregation and additional symbols are added for LDPC encoded RUs. Additional padding bits may be inserted for

The AP 102 - a may calculate the number of distributed payload bits for each available RU of the RU aggregation. The distributed payload bits may include service bits, information bits contained within the PSDU, and padding bits for transmission. In some examples, the AP 102 - a sets the padding bits included in the MAC layer (as part of the MPDU) and the PHY layer (as part of the PPDU) as needed to ensure that the same number of OFDM symbols support timing alignment. It can be assumed that it will be provided to the encoder. For each RU in the aggregation, the AP 102 - a may determine the number of data bits distributed based on the data rate that the RU can support. For example, the AP 102 - a may determine the number of distributed payload bits for an RU of flexible channel aggregation. The AP 102 - a may determine the minimum number of symbols (N _{sym_init} ) included in the DATA field. The AP 102 - a can then determine the number of coded bits (N _bpscs,i ) for each carrier spanning the spatial stream or modulation order of the individual RU and identify the code rate (R _i ). have. In some implementations, the AP 102 - a may determine the data rate of an individual RU and may identify a number of tail bits that may be appended to the data bits according to the data parsing and encoding scheme.

After one or more calculations described above, the parser and encoder associated with the AP 102 - a may distribute the information bits included in the data payload to each RU of the aggregation. In some implementations, the AP 102 - a distributes information bits to each RU in a sequential manner. As part of the sequential distribution, a single information bit may be distributed to individual RUs based on a cyclic process (eg, in a round robin manner), where a first bit is distributed to a first RU in the aggregation followed by subsequent bits. is distributed to additional RUs. When a RU of an allocation (eg, a RU with a small number of available resources) is filled with distributed bits, one or more additional RUs of the aggregation may accommodate the remaining bits for distribution. In other implementations, the AP 102 - a may distribute the information bits by filling the RU of the aggregation with the distributed bits before distributing to one or more additional RUs. Moreover, the AP 102 - a may append tail bits to the data bits of the distribution according to the data parsing and encoding scheme.

Although the described features are provided with reference to downlink single-user PPDU transmission by the AP 102 - a , the STA 10 - a may provide similar operations as part of the uplink single-user communication. have. In the case of OFDMA, the AP 102 - a may perform resource scheduling, and multiple users may perform OFDMA in the downlink or uplink, each user having at least one RU and RU aggregation. handles For example, the STA 104-a may be configured for uplink single as part of a preamble puncturing mode that may be zero-out as part of a PHY preamble that includes a non-primary or primary frequency channel of the extended BSS bandwidth 505 . - Perform user PPDU transmission (ie, at least a portion of the BSS bandwidth 505 may not be available for communication). The STA 104-a calculates the number of OFDM symbols in the DATA field of the PPDU, calculates the number of distributed payload bits for each RU in the aggregation, and transmits over one or more RUs of the flexible channel. It is possible to distribute payload bits for

[0111] A wireless communication device (eg, AP 102 - a, STA 104 - a) may implement a data parsing and encoding scheme for distributing and encoding information bits of a PSDU data payload. In some examples, the wireless device may encode a set of information bits at the PHY layer and may then distribute the encoded set of information bits based on a data parsing scheme. The encoding may correspond to joint encoding in RU aggregation where each RU may have the same coding rate. In other examples, the wireless device may distribute the information bits of the data payload to multiple RUs of the aggregation and perform separate encoding and interleaving for each RU. For example, the MAC layer of the wireless device may perform data parsing between multiple RUs and may pass multiple PSDUs to the PHY layer for encoding. Additionally or alternatively, the MAC layer may pass all information bits of a single PSDU, where the PHY layer may distribute the information bits to multiple RUs for subsequent encoding and interleaving.

6 illustrates an example of a tone plan 600 supporting parser and interleaving parameter design for RU aggregation, in accordance with aspects of the present disclosure. In some implementations, the AP 102 and the STA 104 may use a tone plan 600 for data parsing, in which the tone plan 600 is encoded into data tones of one or more RUs of the tone plan 600 . Distribute the set of information bits. For example, the tone plan 600 may include one or more one tone RUs 610 (eg, used to transmit control information, synchronization information, or as guard periods), one or more two tone RUs 615 (eg, control information). , used to transmit synchronization information or as guard periods), one or more 13 tone RUs 620 (eg, used to transmit control information, synchronization information, or as guard periods), one or more 26 tone RUs 625 ), one or more 52 tone RUs 630 , one or more 102+4 RUs 635 (eg, 106 tone RUs), one or more 242 tone RUs 640 , and 996 tone RUs 645 . may include In some implementations, the tone plan 600 may be used for an HE system using 80 MHz (ie, a HE80 system).

[0113] Additionally, the AP 102 and the STA 104 may differ from the previously indicated in the tone plan 600 to form a single data unit (eg, a single message) communicated between the AP 102 and the STA 104 . The coded bits may be communicated based on an RU aggregation scheme that combines two or more of the RUs. For example, the coded bits may be distributed to one or more RUs of the aggregated set of one or more RUs based on the set of pilot tone locations 605 for the tone plan 600 .

In some implementations, RU aggregation may be applicable for both OFDMA cases and SU transmissions. For example, in the case of OFDMA, the AP 102 may be responsible for resource allocation (eg, for distributing coded bits) for both downlink and uplink transmissions. For downlink transmissions, the STA 104 may be a receiving wireless communication device that receives data from the AP 102 over multiple RUs. For uplink transmissions, the STA 104 may be a transmitting wireless communication device that transmits data to the AP 102 via multiple RUs. Additionally or alternatively, for SU transmissions, RU aggregation may be due to bandwidth puncturing (ie, otherwise the SU transmission would be a transmission across the entire bandwidth). The SU transmission may be a downlink or uplink transmission. Thus, in any case, the transmitter (eg, the AP 102 for downlink transmission or the STA 104 for uplink transmission) may indicate or signal the resource allocation prior to transmitting the downlink or uplink transmission. .

Additionally, one PSDU may be configured per STA (eg, by the AP 102 ). In some implementations, one LDPC encoder may be used in a single MCS case. Additionally, different RU combinations may be allowed for aggregations of small RUs and large RUs (eg, up to 160 MHz bandwidth). In some implementations, larger RU aggregation combinations may or may not be supported for larger size bandwidths (eg, 240 MHz or 320 MHz). In addition to signaling RU aggregations, techniques for how to process such RU aggregations may be provided. For example, a segment parser and interleaving parameter design for RU combinations of RU aggregations may be indicated.

[0116] Different parameters for BCC and LDPC interleaving for various RU sizes are provided according to Table 1 below (eg, for 802.11ax OFDMA).

Table 1 - BCC and LDPC interleaving parameters

In Table 1, the parameter N _SD is the number of data subcarriers for the respective RU size (i.e., the number of tones of the individual RU size that are not pilot tones, where the number of tones is the number of tones for distributing the coded bits of the data unit. available) can be shown. The parameter N _COL may indicate the number of columns for BCC interleaving. The parameter N _ROT may indicate a frequency rotation parameter for BCC interleaving. The parameter N _SS may indicate the number of spatial streams for BCC interleaving. The parameter D _TM may indicate a tone mapping distance (eg, tone mapping distance) for distributing the coded bits for the LDPC encoder to data tones of individual RUs.

Different RU aggregation combinations may be used to distribute and transmit the coded bits from a transmitting wireless communication device (eg, AP 102 ) to a receiving wireless communication device (eg, STA 104 ). For example, different RU aggregation combinations may be used for SU transmissions (eg, when puncturing occurs in one or more RUs) or in OFDMA cases. In some implementations, different RU aggregation combinations may include combining a first RU of a first size and a second RU of at least a second size (2 of different or equal sizes for an RU aggregation combination). more than RUs may be combined). For example, the RU aggregation combination is 26 ton size RU and 106 ton size RU (RU26 + 106 aggregation combination), 484 ton size RU and 242 ton size RU (RU484 + 242 aggregation combination), 26 ton size RU and 52 ton size RU (RU26 + 52 aggregation combination), 484 ton size RU and 242 ton size RU and 484 ton size RU and 242 ton size RU (RU484 + 242+ 484+ 242 aggregation combination). or additional combinations of RUs of different sizes not listed herein.

Based on various possible RU aggregation combinations, different segment parsers may be required to distribute the coded bits for different RU aggregation combinations. However, using various segment parsers for distribution of coded bits based on a corresponding RU aggregation combination may increase computational complexity at either the AP 102 or the STA 104 , or both. For example, the STA 104 may need to know different types of segment parsers that may be used by the AP 102 to monitor the coded bits and distribute the coded bits to identify where to receive the coded bits. can Thus, examining each of the different segment parsers not only increases the latency when the STA 104 (or any receiving wireless communication device) receives and decodes a data unit, but also allows the STA 104 to perform different types of segment parsers. It can increase the computational complexity when storing and identifying them.

In some implementations, the AP 102 and the STA 104 may use an 80 MHz segment parser to distribute the coded bits to one or more RUs in an RU aggregation combination. The 80 MHz segment parser can be used with existing designs for bandwidths greater than 80 MHz so that hardware for each 80 MHz segment parser is present in wireless communication devices. When using each 80 MHz segment parser, RU aggregation of different parameters for parsing (eg, 484 tone RU and 242 tone RU (484 + 242 RUs)) for large RU aggregation combinations combination) can be determined. For example, the D _TM value may be determined for large RU aggregation combinations. In the absence of a respective 80 MHz segment parser, different D _TM values may be required for each aggregation bandwidth mode. For example, different aggregation bandwidth modes may include 60, 100, 120 or 140 MHz up to 160 MHz (and possibly larger variants with 320 MHz). Thus, a modification using an 80 MHz segment parser may be less complex than designing individual D _TM values for different RU aggregation bandwidths.

[0120] Additionally, each 80 MHz segment parser may be extended to cover puncturing (ie, a portion of each 80 MHz segment or at least one RU may be of one type such that the RU or portion is not available for parsing). reserved for communications). In some implementations, different 80 MHz segments may carry different numbers of bits due to puncturing or other factors that limit or expand the number of bits available in 80 MHz segments. As a result of different numbers of bits that can be carried in different 80 MHz segments, the round robin segment parsing scheme can be extended.

For example, an even distribution of coded bits may be used between 80 MHz segments, where half the number of coded bits per single carrier for each spatial stream (N _bpscs /2) is equal to the first 80 MHz segment, and then half of the number of coded bits per single carrier for each spatial stream (N _bpscs /2) is distributed to the second 80 MHz segment. Additionally or alternatively, the distribution of coded bits may be extended to a larger number of segments for parsing (eg, three 80 MHz segments with one third of the number of coded bits are divided into three segments). 4 80 MHz segments with 1/4 of the number of coded bits are divided into 4 segments, and so on). In some implementations, when a smaller segment is filled, the remaining bits may be distributed among the larger segments.

[0122] Using each 80 MHz segment parser that uses RU aggregation (eg, as defined by 802.11be), the D _TM value is different for different RU aggregation combinations (eg, large RU aggregation). for the cases of RU484 + 242 aggregation combination for aggregation and RU26 + 52 or RU26 + 106 aggregation combinations for small RU aggregation) can be determined and defined. In some examples, for different combinations or RU locations, the same D _TM value may be used for any combination of aggregated RUs with the same aggregation bandwidth, regardless of the location and size of each RU. . For example, the RU484 + 996 aggregation combination (i.e. 40 MHz bandwidth + 80 MHz bandwidth) and RU484 + 242 + 484 + 242 aggregation combination (i.e. 60 MHz bandwidth + 60 MHz bandwidth) would use the same D _TM value. can Additionally or alternatively, the RU242 + 242 aggregation combination (ie, 20 MHz bandwidth + 20 MHz bandwidth) and RU484 (ie, 40 MHz bandwidth) may use the same D _TM value.

[0123] In some implementations, the distribution of coded bits to data tones of RUs in an RU aggregation scheme may be based in part on a D _TM value. For example, the D _TM design may be directly related to the number of data tones provided by the RU aggregation scheme. Thus, for a given aggregation bandwidth, the number of pilot tones may be determined after aggregation of RUs, and the remaining tones may be considered data tones for distributing the coded bits. For smaller sized RUs (eg, 26 ton, 52 ton and 102 +4 ton RUs), fewer pilot tones may be located in each RU. For example, 2 pilot tones may be configured for a 26-tone size RU, 4 pilot tones may be configured for a 52-tone size RU, and 102 + 4-tone size RU (106-tone size). 4 pilot tones can be configured for RU of .

Thus, if fewer pilot tones are located in these smaller sized RUs, one or two pilots to distribute the coded bits to the aggregated set of smaller sized RUs. Changing tones to data tones may not provide much advantage. Thus, for aggregations of smaller sized RUs, the existing pilot tones of each RU of the RUs combined into the aggregated RUs are maintained for tone configuration (eg, as part of tone plan 600 ). can be Different interleaving parameters may depend on the number of pilot tones and the resulting number of data tones in the RU (eg, the total number of tones in the RU minus the number of pilot tones equals the number of data tones). For example, the different interleaving parameters may include a D _TM parameter, pilot tone locations 605 , N _COL parameter, or additional parameters used to interleave and distribute coded bits to aggregated RUs.

[0125] For example, the D _TM design for the first aggregated RU (A-RU) is 52 tone RU630 (RU26 + 52) to create an A-RU with 78 (26 + 52 = 78) tones. ) and an aggregated 26 ton RU625. Additionally, the number of pilot tones of an A-RU with 78 tones (A-RU78) may be 6 pilot tones (e.g., 2 pilot tones of 26 tone RU625 and 4 pilot tones of 52 tone RU630), Accordingly, the number of data tones in A-RU78 is equal to 72 data tones (26 + 52 = 78 total tones - 6 pilot tones = 72 data tones). Based on 72 data tones, interleaving parameters for D _TM design for this first A-RU may include (eg, based on 72 = 18 * 4) D _TM = 4 and N _COL = 18 . That is, the existing pilot tones and data tones of the individual RUs of the A-RU (for smaller RUs) may be used to determine the D _TM design for the A-RU. This D _TM design can be aligned with D _TM designs for other data block sizes.

Additionally or alternatively, the D _TM design for the second A-RU may include a 26 tone RU625 aggregated with a 106 tone RU (eg, 102 + 4 tone RU635). Thus, an A-RU may contain 132 total tones (RU26 + 106 = A-RU132), and 6 pilot tones (eg, 2 pilot tones of 26 tone RU625 and 4 pilot tones of 102+4 tone RU635). tones), thus the number of data tones of A-RU132 is equal to 126 data tones (ie, 26 + 106 = 132 total tones - 6 pilot tones = 126 data tones). Based on 126 data tones (eg, 2 * 3 * 3 * 7 data tones), the interleaving parameters for the D _TM design for this second A-RU are (eg, based on 126 = 18 * 7) D _TM = 7 and N _COL = 18, or (eg, based on 126 = 21 * 6) D _TM = 6, N _COL = 21. Similar to the D _TM design for the first A-RU, this D _TM design may be aligned with the D _TM designs for other data block sizes.

[0127] In the case of aggregations of larger size RUs or larger block sizes (eg, 242 tone RUs 640 , 484 tone RUs and 996 tone RUs 645 ), The density may be lower than the density for smaller sized RUs. For example, 8 pilot tones may be configured for a 242 tone RU 640 (RU242), 16 pilot tones may be configured for a 484 tone RU (RU484), and 16 pilot tones may also be configured for a 996 tone RU 645 (RU996). ) can also be configured. Thus, changing one or more pilot tones to data tones for an A-RU of larger sized RUs (e.g., pilot Puncture of pilot tones to reuse the tones as data tones) may provide greater impact and advantages over A-RU of smaller RUs. For example, for a third A-RU comprising a 242 tone RU640 and an aggregated 484 tone RU (RU484 + RU242), different options for determining the number of pilot tones (and consequently pilot tone locations 605 ). may be available.

[0128] In some implementations, similar to the techniques described above with reference to smaller sized RUs in the A-RU, the existing pilot tones of each RU of RUs combined into aggregated RUs are ( For example, as part of the tone plan 600) may be maintained for tone configuration. For example, for the third A-RU, the total number of tones may be 726 tones with 24 pilot tones (eg, A-RU726 = RU484 + RU242) (eg, 242 tone RU640 with 8 pilot tones) 484 tone RU may include 16 pilot tones), so the number of data tones of the third A-RU (A-RU726) is equal to 702 data tones (ie, 484 + 242 = 726 total tones - 24 pilot tones = 702 data tones).

Additionally or alternatively, a subset of the total number of existing pilot tones may be punctured and reused as data tones to increase the number of data tones. For example, in the case of tone plan 600 (80 MHz tone plan), 16 pilot tones may be punctured, leaving 16 pilot tones for 996 tone RU 645 (RU996) with lower pilot tone density. . Then, for a third A-RU with a low pilot tone density (e.g., A-RU726 = RU484 + RU242), the pilot tones used in the 996 tone RU645 may be used, but a subset of the pilot tones may be punctured. have. In some implementations, the subset of pilot tones may be, for example, 4 pilot tones from a punctured 20 MHz segment of a total 80 MHz tone plan. Therefore, the number of pilot tones is 16 - 4 = 12 in the 3rd A-RU. For example, in the case of the third A-RU, the total number of tones may be 726 tones with 12 pilot tones (A-RU726 = RU484 + RU242), so that of the third A-RU (A-RU726) The number of data tones is equal to 714 data tones (ie, 484 + 242 = 726 total tones - 12 pilot tones = 714 data tones).

In some implementations, some pilot tones are punctured, such that data tones that are not available based on being located in the punctured portion of the tone plan 600 (eg, puncturing of the tone plan 600 ) It can be reused as data tones to replace data tones that stick out into the subband. For example, when the first portion of the tone plan 600 (ie, the first 20 MHz subband of the 80 MHz tone plan) is punctured, the second portion of the tone plan 600 (eg, the first portion) protrudes into the first portion. , the two left edge data tones in the second 20 MHz subband) may be unreliable. Accordingly, the two pilot tones may be used as data tones to compensate for the loss of the two left edge data tones in the punctured portion of the tone plan 600 . Additionally or alternatively, when the fourth portion of the tone plan 600 (eg, the fourth 20 MHz subband in the 80 MHz tone plan) is punctured, the fourth portion of the tone plan 600 that protrudes into the fourth portion is punctured. The three right edge data tones in the three part may be unreliable, and the three pilot tones may be used as data tones to compensate for the loss of the three right edge data tones in the punctured part of the tone plan 600 . .

[0131] The total number of tones may then be 726 tones with 21, 22 or 24 pilot tones (A-RU726 = RU484 + RU242). For example, the total number of pilot tones may be 24, a 242 tone RU640 may contain 8 pilot tones, and a 484 tone RU may contain 16 pilot tones, 2 or 3 of the total number of pilot tones. may be reused as pilot tones based on one or more data tones located in the punctured portion of tone plan 600 as described above. Thus, the maximum number of pilot tones may be 24 (eg, if no data tones are located in the punctured portion of tone plan 600 ), so that the number of data tones in the third A-RU is may equal 702 tones (ie, 484 + 242 = 726 total tones - 24 pilot tones = 702 data tones).

[0132] Based on these different options for determining the total number of data tones for a third A-RU (eg, A-RU726 or larger sized RUs in an A-RU), this third A-RU The interleaving parameters for the D _TM design for the RU may be different. For example, in the case of the above-described options where 702 data tones are available (e.g., based on the total number of pilot tones in each RU of the third A-RU or one or more data tones are punctured in the tone plan 600 ) In case the subset of pilot tones is punctured based on what is in the given portion), the D _TM design for the third A-RU (A-RU726) is based on the interleaving parameters (eg, based on 702 = 18 * 39) D _TM = 18 and N _COL = 39. Additionally or alternatively, in the case of the previously described option in which 714 data tones are available (e.g., based on the punctured subband and based on reusing a subset of the remaining pilot tones in the 996 tone RU): The D _TM design for the third A-RU (A-RU726) is (eg, based on 714 = 17 * 42 or 14 * 51) interleaving parameters D _TM = 17 and N _COL = 42 or D _TM = 14 and N _COL = 51.

Additionally, these D _TM designs may be aligned with D _TM designs for other data block sizes. In some implementations, the determination of different D _TM values may be based on the D _TM values listed in Table 1 above, where 14, 17, and 18 are currently unused for different RU sizes, and 484 tone RU. and D _TM values of 996 tone RU (eg, D _TM = 12 for 484 tone RU and D _TM = 20 for 996 tone RU).

7 illustrates an example of a physical RU partitioning 700 that supports interleaving parameter design and a parser for RU aggregation, in accordance with aspects of the present disclosure. In some implementations, the AP 102 and the STA 104 perform data parsing to distribute the encoded set of information bits to the data tones of one or more RUs of the RU aggregation combination based on the physical RU partition 700 and An interleaving method may be used. The physical RU partition 700 may include one or more RUs 710 and a tone plan 705 for one or more RUs 715 . For example, tone plan 705 may be an 80 MHz tone plan, where one or more RUs 710 represent 242 tone RUs and one or more RUs 715 represent 13 tone RUs (eg, these tone RUs are used to transmit control information, synchronization information or as guard periods).

The tone plan 705 may be partitioned to include four RUs 710 , but the four RUs 710 are equal to one or more physical partitions 720 (eg, 20 MHz boundaries). may not be spaced apart. For example, the first RU 710 - a (eg, the first 242 tone RU) is 2 far from the left boundary (eg, the first 20 MHz boundary) of the first physical partition 720 - a of the tone plan 705 . It can be located with tones. Additionally, the second RU 710 - b (eg, the second 242 tone RU) has one or more overflow tones 725 - a (eg, a 20 MHz boundary) that crosses the left boundary of the second physical partition 720 - b . 2 tones beyond ).

[0136] In some implementations, the 7 direct current (DC) tones (eg, 13 tone RUs) between the first RU 715-a and the second RU 715-b are divided into a third physical partition ( 720-c) by a left boundary (eg, a 20 MHz boundary) into 3 and 4 tones. Accordingly, the three or four DC tones of the individual physical partitions 720 may or may not be sufficient DC tones to serve as a guard band for the physical partitions 720 . Additionally, the third RU 710 - c (eg, the third 242 tone RU) is a right boundary of the third physical partition 720 - c (eg, a 20 MHz boundary or a left of the fourth physical partition 720 - d ). one or more overflow tones 725 - b (eg, three tones) beyond the boundary). In some implementations, the fourth RU 710 - d (eg, the fourth 242 tone RU) may be 3 tones away from the right boundary (eg, 20 MHz boundary) of the fourth physical partition 720 - d have.

Thus, based on the overflow tones 725 , if one of the physical partitions 720 (eg, 20 MHz subbands of an 80 MHz tone plan) is punctured (eg, a legacy wireless communication device or otherwise not available for use), the overflow tones may not be available for use in the RU aggregation combination.
